SLAUGHTERING DEVICE.

Application filed 'March 24, 1924. Serial No. 701,386.

Toul] whom if, '1n/ay concern Be it known that I, ELMER E. HIGMAN,

= a citizen of the United States, residing at Kansas City, in the county of lVyaiidotte and State of Kansas, have invented certain new and useful Improvements in Slaughtering Devices, of which the following is a specification.

My invention relates to improvements in slaughtering devices andI one object is to provide a knife whereby animals may be slaughtered in a swift, sanit-ary and humane manner.

A furthei object is to provide aslaughtering device whereby the blood may be drawn from the 'arteries and veins of the animal and conducted directly to a sealed container without exposure to dust, bacteria of thev air, or other contamination, thereby rendering the blood especially desirable for use in the preparation of serum.

Other objects will hereinafter appear, and in order that the invention may be fully understood, reference will nowbe had to the accompanying diawing, in which:-

Fig. 1 is an elevation of the slaughtering device. v

Fig. 2 is a longitudinal section thereof on line II-II of Fig. 1.

Fig. 8 is a cross section lon line III- III of Fig. 1.

Referring now in detail to the various parts, 2 designates 'a tubular body having an extension 4 projecting at an angle therefrom and provided with an outlet port 6; Said tubular body 2 is provided at its forward end with a removable'extention 8 having inlet ports 10. The forward end 12 of the extension 8 is of conical formation and has a slot, 18 to receive the rear end of a blade 14 having tapered lugs 16, which are through which a valve stem 22 axially extends. The rear end of said valve stem v'22 is provided with a handle 24, while its` forward e1id,`which projects intothe tubular body 2, is equipped with a valve 26 yield.-`

ably held againsta shoulder 28 on the. stein` 22 by a coil spring 30, which is held ii-nl position by a nut and washer-32 and 64 respectively, on the forward end of said stem 22.

The valve 26 is provided at its front and rear margins with cut-ting edges .86, which 'fit snugly but slidably within the extensionA 8 and coact with an annular blade 38 in preventing the inlet ports 10 from becoming clogged as will hereinafter appear. The annular blade 38, which slidably embraces the extension 8, has front and rear cuttingy edges 40 and 42, respectively, and is connected to the valve 26 by suitable means such as screws 44 which extend through the inlet ports 10. vf

The valve 26 is normally held to its seat V46 to shut olf communication between the inlet ports 10 and the outletport 6 through the action of a coil spring 48 bearing at one end against a shoulder 50 `in the rear portion `of thelhandlc 20" and at its opposite.V end against `a disk 52, slidably arranged within the handle 2O and secured to the valve stem 22 by suitable means such as a pin 54.,

56 designates a latch adapted to lit into a notch l58 in the valve stem 22 to hold the' saine in retracted position against the action of the spring 48 and to normally hold the valve 26 against its seat 46 in order to closc communication between the ports 10 and 6.

The latch 56 is controlled by a small lever 60 pivotally connected to the rear portion of the handle 20. A coil spring 62 is interposed betweeii the handle 2O and the lever 60 to cause the same to yieldably hold the latch 56 in the notch 58. The valve stem 22 is also provided with a notch 64 at the 4rear of the notch 58, so that said valve stem 22 and the valve 26 may be locked in their forward position.

The rear end of the tubular body 2 is provided with a stutling-box 66 to form a tight joint around the valve stem 22. A leather of other suitable washer 68 is seated in the valve 26 around the stem 22, to receive theV thrust of the spring 30 and preventy blood. from thel slaughtered animal entering the axial opening -in the valve 26'where it would congeal Vand. preventk the spring 30 from cushioning said valve 26' when the saine is drawn against its seat y46.v

The extension 4 of the tubular Abody 2 is equipped with a hose 70, which may-be connected to a sealed container, not-shown.

7 2 designates a curvedr retaining device nov which is connected at its rear end by a pivot "4 to the valve and has @its forward end extending' through a` hole 7G in the forward portion of the extension 8.

In practice a hog or other animal lmay be slaughtered and its blood conducted to the container as follows: lith the parts inthe position shown by Fig. the blade le is plunged into the throat of the animal to sever the liugular vein, the device being insorted in the wound up to the extension 1l. After the blade le has been thrust home the same hand which g asps the handle 22 actuates the lever (5t) to discng'age the latch from the valve stem 22, which is immediately forced forward by the spring #i8 and carries the valve 26 therewith to establish communication between the inlet ports-l0 and the outlet port (i. 'lhe blood may now tlow freely from the wound into the container to which the hose TO is connected, which container' is preferably under a vacuum that quickly draws the blood from the animal. The wound is held open by the tubular extension S, so that the blood may Atiow freely until all has been drained into the container.

lVhen the valve Q8 is forced forwardly by the action of the spring- 48, as above stated, it forces the retainer 72 outwardly through the hole 76 and int-o the wound at substantially right angles to the blade lll, for the purpose of reliably holding the same in the wound. This leaves the operator free to plunge other of the devicesl into other ani.- mals as they are carried past by suitable means, such as an overhead rail, to another operator who removes the devices from the slaughtered animals after the blood has been drained therefrom.v

During the act of withdrawing; the devices from the slaughtered animals the handles 24 are tirst pulled lnickvardly to withdraw the respective retainers T2 from the wounds, after which the device can be easily removed by pulling back on the handle 2t), after the latch has been withdrawn from the notch tiet.

From the foregoing description it is apparent that have provided a slaughtering device embodying the :uilvantae'es above minted out; and while I have shown'and descrilred the preferredconstruction, combitubular body having inlet andout ett a valve operably -inount'ed'l 1 n sain* fflprlt's, cutting-means-inovableaei L nation and arrangement of parts,`l reserve .the right to make such changes as properly fall within the spirit and scope of the invention asclaimed.
